Technical Field

The invention relates to the field of fabric dyeing and finishing, in particular to a cylinder cleaning agent of a high-temperature jig dyeing machine, which does not corrode a cylinder body, has a good cylinder cleaning effect and saves cost, and an application thereof.

Background

With the increasingly strict monitoring of the environment-friendly production of the printing and dyeing industry in China, energy conservation and emission reduction become the key points of the long-term development of the printing and dyeing industry. The existing dyeing and finishing process of polyester fiber woven fabrics commonly used for some umbrella surface fabrics is desizing and then dyeing, compared with the dyeing and finishing process, the one-bath dyeing process has the advantages of shorter process flow, lower energy consumption and cost and better accordance with the current environment-friendly trend of energy conservation and consumption reduction.

With the popularization of the one-bath dyeing process in a dyeing workshop, a plurality of dark color machine cylinders, especially black machine cylinders, are used for a long time, a large amount of dirt and scale are deposited in the machine cylinders, color points are easily generated, the dirt is cleaned in a conventional liquid alkali and protective powder mode, the effect is worse and worse, through analysis, the components of the dirt are mainly calcium hydroxide, calcium sulfate and the like, the dirt mainly comes from water quality and dye, the dirt is basically ineffective through conventional acid alkali treatment, only citric acid is used for cleaning, and the scale has a certain effect, so that the quality of products is greatly influenced.

However, only citric acid is used for cleaning, the using amount is large, the rest of auxiliary agents are required to ensure the dirt removing effect, and the cleaning process is complicated.

Disclosure of Invention

The invention aims to solve the defects that only citric acid has a certain effect in the existing deep color cylinder cleaning process, but the consumption of citric acid is large, and provides a cylinder cleaning agent for a high-temperature jig dyeing machine, which does not corrode a cylinder body, has a good cylinder cleaning effect and saves cost, and an application of the cylinder cleaning agent.

In order to achieve the purpose, the invention adopts the following technical scheme:

the cylinder cleaning agent for the high-temperature jig dyeing machine comprises the following components in parts by weight: 20-80 parts of organic acid, 10-20 parts of sodium dodecyl benzene sulfonate, 3-10 parts of sodium dodecyl sulfate and 10-60 parts of water. In the technical scheme, the inventor analyzes the components of the dirt, wherein the components mainly comprise calcium hydroxide, calcium sulfate and the like, and adds an emulsifier and a dispersant into a cylinder cleaning agent to prevent the dirt cleaned from being reversely adhered; through neutralization reaction, the cylinder body is not corroded, the cylinder cleaning effect is good, and the application performance is excellent; the cylinder cleaning agent is acidic, has good effect when used alone, and is not used together with other additives.

Compared with the conventional acid washing and sodium hydrosulfite cleaning modes, the method has extremely excellent effect of cleaning the scales of the machine cylinder, can be used for directly dyeing production after hot water in the cylinder is cleaned after the cylinder cleaning is finished, saves the cost and has better effect.

Preferably, the organic acid is oxalic acid and citric acid in a mass ratio of 3:1-2: 1. In the technical scheme, the oxalic acid is also called oxalic acid and is widely present in plant source food. Oxalic acid is colorless columnar crystal, is easily soluble in water but not soluble in organic solvents such as diethyl ether and the like, has strong coordination effect, and is another metal chelating agent in plant-derived food. When oxalic acid is combined with some alkaline earth elements, its solubility is greatly reduced, e.g., calcium oxalate is practically insoluble in water. The presence of oxalic acid therefore has a great influence on the bioavailability of the essential minerals.

By matching oxalic acid with citric acid, the effect of removing the scale on the cylinder is improved.

Preferably, the cylinder cleaning agent for the high-temperature jig dyeing machine comprises the following components in parts by weight: 40-60 parts of organic acid, 12-15 parts of sodium dodecyl benzene sulfonate, 5-8 parts of sodium dodecyl sulfate and 20-40 parts of water.

Preferably, the cylinder cleaning agent for the high-temperature jig dyeing machine comprises the following components in parts by weight: 30 parts of oxalic acid, 10 parts of citric acid, 13 parts of sodium dodecyl benzene sulfonate, 7 parts of sodium dodecyl sulfate and 40 parts of water.

Preferably, the pH value of the high-temperature jig dyeing machine cylinder cleaning agent is 2-3.

The cylinder cleaning agent for high temperature jig dyeing machine is applied through adding water into the cylinder of the jig dyeing machine, the water amount exceeds the dyeing capacity, adding the cylinder cleaning agent into the water, stirring and filtering intermittently, controlling the cylinder cleaning time within 8 hr +/-5 min, and maintaining the water temperature over 95 deg.c during the cylinder cleaning process.

Preferably, the cylinder cleaning agent of the high-temperature jig dyeing machine is added in an amount of 5kg per 100L of water.

Preferably, the vat cleaning agent of the high-temperature jig dyeing machine is added and then stirred for 5 minutes, the mixture is stirred and then kept stand for 2 hours, the second stirring is carried out after the standing is finished, the second stirring time is 5 minutes, the filtration is carried out while the second stirring is carried out, a filter screen is extended into the jig dyeing machine and synchronously rotates along with a stirring paddle, the mixture is kept stand for 3 hours after the second stirring, the third stirring is carried out after the standing, the third stirring time is 5 minutes, the filtration is carried out while the third stirring is carried out, and the mixture is kept stand for 2 hours and 45 minutes after the third stirring.

In the process of cleaning the vat, the modes of stirring, standing and filtering are combined, the inner wall of the jig dyeing vat is washed by water flow, and the dirt washed off is filtered by a filter screen, so that the effect of cleaning the vat is improved.

The invention has the beneficial effects that:

according to the invention, through neutralization reaction, the cylinder body is not corroded, the cylinder cleaning effect is good, and the application performance is excellent; the cylinder cleaning agent disclosed by the invention is acidic, has a good effect when being used alone, and is not used together with other auxiliaries; compared with the conventional acid washing and sodium hydrosulfite cleaning modes, the method has extremely excellent effect of cleaning the scales of the machine cylinder, can be used for directly dyeing production after hot water in the cylinder is cleaned after the cylinder cleaning is finished, saves the cost and has better effect.
